DANGER Risk of fire  due to ignition of R1234yf refrigerant on hot components. Risk of poisoning  caused by inhaling overheated refrigerant vapors. Risk of injury  to skin and eyes caused by contact with escaped R1234yf refrigerant and when working on pressurized parts. Risk of explosion  due to formation of ignitable refrigerant/air mixtures Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated rooms. Carry out repair work on the air conditioning system circuit only after the system has been evacuated. AS83.00-Z-0007-01A 
WARNING Risk of poisoning  caused by inhaling overheated refrigerant vapors from an air conditioning system containing R134a. Risk of injury  to skin and eyes caused by contact with liquid R134a refrigerant and when working on pressurized parts Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated rooms. Carry out repair work on the air conditioning system circuit only after the system has been evacuated. AS83.00-Z-0006-01A

  Evacuate     
6 Clean refrigerant and evacuate refrigerant circuit.    
7 Conduct vacuum test using air conditioning service unit.    
  Filling     
8 Add new compressor oil to the refrigerant circuit according to the oil filling capacity noted during extraction.    
REFER TO CAPACITIES & SPECIFICATIONS Compressor oils (specification 362.1)   BB00.40-P-0362-01A
    NOTES
Only use the approved compressor oil. If it is proven that a different compressor oil has been used, we will refuse to reimburse costs within the warranty and goodwill period. Daimler AG reserves the right to perform reexaminations.		  
    NOTES
Correct oil filling quantity in refrigerant circuit. An incorrectly measured oil filling capacity leads to damage to the refrigerant compressor.		  
    IMPORTANT Depending on the repair case, the oil filling quantity may need to be adjusted accordingly.
